RockinEVeSeems silly to watch TV to ensure the passage of time — the clock will strike midnight on your wrist as sure as it will on Times Square. But 2019 will be ushered in with a growing number of TV specials that seem to be starting earlier and earlier.

“Dick Clark’s Primetime New Year’s Rocking’ Eve with Ryan Seacrest” (ABC, 8 p.m.) is not only the longest of the current specials; it also has the longest title. Among the performers all night from Times Square will be Bastille, Dan + Shay, New Kids on the Block and Christina Aguilera. The ever-annoying Jenny McCarthy, now known as Jenny McCarthy Wahlberg, will report from the street and distribute questionable information about immunization. Ciara hosts from Hollywood, Lucy Hales is in New Orleans.

Serving up different music is the New York Philharmonic conducted by Jaap van Zweden playing “Live from Lincoln Center” (PBS, 9 p.m., check local listings) with an appearance with opera’s Renée Fleming.

And its own genre will be the rock and Americana in the Austin City Limits Hall of Fame New Year’s Special (PBS, 10:30 p.m., check local listings) inducting Ray Charles, Marcia Ball and Los Lobos. Chris Isaak hosts a roster that includes Norah Jones, Gary Clark Jr. and Robert Randolph.

But what of the “Thin Man” series with which they usually ring out the year? They’re earlier in the day with “The Thin Man” (8:45 a.m.), “After the Thin Man” (10:30 a.m.), “Another Thin Man” (12:30 p.m.), “Shadow of the Thin Man” (2:30 p.m.), “The Thin Man Goes Home” (4:15 p.m.) and “Song of the Thin Man” (6:15 p.m.).
